Application filed March 11, 1918. Serial El 0. 22135283.

V21 lll i e following is a specification. invention pertains more particularly ops ot' the character employed for binding s piece of hose onto a nipple or pipe. and the object of the invention is to provide a simple and inexpensive clamp cabeing quickly and efficiently spreadily ada table to different ose or other articles to which it may be applied.

'@ne of the main purposes of the invention is to provide an efficient and inexpensive clamp capable of being readily adjusted for and epplic to varying diameters of hose or ri s and o to hose varying in the plies 3i? and requising clamps varying in *ength. A further purpose of the invention is to ovide a hose clamp formed of flexible sheet metal which may present substantie uniform surfaces to the hose.

The c mp or", my invention comprises a xible body portion, opposed heads at adj-scentends thereof and incens for l t said heads toward each other for said body portion on the hose, towith other details to be hereinafter The invention will be fully understood from the detailed description hereinafter presented. reference being had to the accom-' panving drawings, in which:

In the drawings, 10 designates a piece of hose'with theclamp of my invention applied thereon and binding the same upon a piece of piping or a nipple 11', and the said clamp5 in the preferred construction thereof, comprises two flexible metallic strips 12, 13., heads lat, 15' at adjacent ends of said strips 12, 13, a coupling 16 at the other adjacent ends of said stripe. a screw 17 extending through said heads and a nut 18 engaging one of said heads and being engaged by said screw. constructed for hose requiring a strength of clamp in addition to that afforded When the ll hen the clamp is to be head 15 alone is employed, I will make use use of a supplemental head 20 appli'e ""dle'po'rtions of said bridge piece and bent 66 against the head 15, whieh'zisiintegrali'witlrrwoutwardly,gas will-be understood on refer- V the bridge tongue 29. ence to Figs. 1, 2 and; 3, and sa1d bridge .Referring to Figs. 1 and 2, the 'strips 12; piece 29 at opposite sides of the opening 13 at their ends removed from the securing f33tformed therein by cutting the head 15 wiflfi jr izrgmi t gea togethe Ky? -tlie therefromis corrugated, as at 3 1, so as to coupling 16, shown in detail in ig ;5 sa1d strengthenLthose portions of the metal at endsv of said strips being'inse'rted through opposlt-e-sldes of sa1d open ngandadncent theopen ng :21 e-fieid; ell pli ,anvd-;; -17et0 sa1d head 10 versely turned" 1nd 2 The head. lfl s shown more particularly in i Fig. 6., andvon referenceto Fig. 6 it will be iqedthat;thef ro sr 2 of the base member26 is, recessed upwardly to afford a; space for the thickness of the innerlayer of 4 v I gthemetalqstrip,'12,, whereby the downward t d,barsfle fasei zear 1-. i !Q -..=P 1 ..@ti o m id ck s of me dengage the exteriorsu'rface of sai hos ll i.,ed{vand;,the 'lampmay have a more eflicient this;being importangin securingagas tlfglrt binding -"actionl-., Iherecessing outwardly connectio of,th 1 nipple endSTIJOL the criossbar 25 permits. the free end of 20 ofJthej I'ted: th ough the.; ong ue. nbridge-piece 29 to lie close couplin be against the f ae e of the adjacent portion of m tni s ethe l i eater-.12..

it In Figs. 10 a nd 111' illustrate a modificaf the invention, the clamp there shown v g in oneintegral strip of flexible metal, ha pne en d bent outwardly to form ag-ext'e'nd'ed to'form abridge piece or tongue39 adapted to pass below fthatend ofthe stripfrom which the head willoiiiit the head-19 and allow 1; e head of ios' e nut 37 andscrmv 38, and the 36 is formed. The metal strip as a whole is numbered 40 and at the bridge piece or tongue 39 the metal of said strip is cut and bent outwardly to form the lip or bearing head 41 for the head of the screw 38. The lip or bearing head 41 corresponds exactly with the lip or bearing head cut from the tongue or bridge-piece 29, and in fact the bridge-piece or tongue 29 is duplicated at the end of the stri 40. The end of the strip 40, below which t e tongue or bridge piece 39 passes, is recessed, as at 42, to accommodate the end of said tongue or bridge-piece and permit the strip 40 to, with substantial uniformity, bind against the hose. What I claim as my invention and desire to secure by Letters Patent, is

1. A clamp of the character described, comprising two flexible metal strips, a oupling having cross-bars around which the ends of said strips at one side of the clamp are folded inwardly and which permits of the adjustment of the diameter of the clamp, heads at the other ends of said strips, crossbars at said heads around which said other ends of said strips are folded inwardly and at which the length of said strips may be adjusted to vary the diameter of the clamp,

and means at said heads for tightening the clamp on the hose.

2. A clamp of the character described, comprising two flexible metal strips, a coupling having cross-bars around which the ends of said strips at one side of the clamp are folded inwardly and which permits of the adjustment of the diameter of the clamp, heads at the other ends of said strips, crossbars at said heads around which'said other ends of said strips may be adjustedito vary the diameter of the clamp, and means at said heads for tightening the clamp on the hose, said coupling having end bars which are adapted to engage the hose and having its cross-bars offset outwardly to accommodate the thickness of the metal strips so as to permit a close binding action of the strips at said cross-bars against the hose.

3. A clamp of the character described,

comprising a flexible metal body portion,

heads at the ends-thereof at one side of the clamp, a tongue .or bridge-piece spanning the space between said heads, and means at said heads for tightening the clamp upon the hose, one of said heads being slit and stamped up from said tongue or bridgepiece, while the other head is of angular formation and slotted in its base portion to receive one end of said body portion, said tongue or bridge-piece being at opposite sides of the opening from which the head is slit and bent outwardly therefrom, 1ongitudinally corrugated.

4. A clamp of the character described, comprising a flexible metal body portion, heads at the ends thereof at one side of the clamp, and means at said heads for tightening the clamp upon the hose, one of said heads being of substantially right angular formation and having a base portion which is slotted to admit one end of said body portion and create a cross-bar around which said end is folded, and said cross-bar being recessedbutwardly to receive the thickness and width of said end.

5. A clamp of the character described, comprising a flexible body portion, a bearing head at one end thereof, abridge-piece connected with the other end thereof and affording a head and adapted to span the s ace between said heads, a substantially right angular head applied upon said bridge-piece and against the head afforded thereby, and a screw and nut for drawing the heads at opposite ends of said body portion toward each 'other for tightening the clamp upon the hose, said bridge-piece and the base-member of the head applied thereon being correspondingly slotted to receive their end of said body portion and permit said end to be wrapped around the crossbars created by said slots.

6. A clamp of the character described, comprising a flexible body portion,- a bearing head at one end thereof, a bridge-piece connected with the other end thereof and affording a head and adapted to span the space between said heads, a substantially right angular head applied-upon said bridgepiece and against the head afforded thereby, and a screwand nut for drawing the heads at opposite ends of said body portion toward each other for tightening the clamp upon the hose, said bridge-piece and thebase-member of the head applied thereon ISIDOR COOPER.
